provements in Safety-Razors, of which the following'is a specification.

My invention relates generally to improvements in safety razors, and ismore particularly concerned with means for adjustably retaining theblade in position ina safety razor. 7

The present invention may be used with a number of types of safetyrazors, but its particular application is in connection with the 'typeof folding safety razor forming the subject matter of a copendinapplication for patent, Serial Number 29 ,252 filed May 15, 1919, in thenames of Winfred H. Van Gorder and Christian E. H, Gronbech.

Stated in general terms, the invention comprises a blade holder, inWhich'the blade may be adjusted, such blade holder provided with meanscooperating with complemental means in a part of the razor for securelyretaining the, blade in adjusted position in the razor;

- The invention is illustratively exemplified in the accompanyingdrawing, in which like letters of reference refer to like partsthroughout, and wherein Figure 1 is a perspective view of part of afolding safety razor with the blade about to be placed in positiontherein. Fig. 2 is a sectional elevation, the blade being shown abovethe base plate of the razor in one position, and resting on the baseplate in a second, dotted line position, and Fig. 3 is a bottom planview of the blade and its holder.

As stated above, the invention may be used in a variety of types ofrazors, and that shown in the drawing is a folding safety-razorcomprising a base late 10, having hinged to one end thereo a cover plate11 and a handle member 12. A fragment only of the cover plate 11 isshown, and at the outer end of the complete plate 11 is another handlemember like 12 but which it is deemed unnecessary to show in thedrawing. The base plate 10 is provided with guard teeth 13, such teethappearing at only one of the longer sides of the base plate 10 althoughit is obvious that, if desired, both longer sides of the plate may havesuch guard teeth.

The blade 14, which is provided with one cutting edge 15 although it maybe provided with two if preferred, is adjustably mounted in a bladeholder consisting of a strap. or band 16 the opposite ends 16 of whichare turned .or lapped over the opposite ends 14 of the blade. The'band16 is considerably narrower than the blade, and the latter is fairlytightly held in the band although capable of lateral adjustment.

therein.

Adjacent the ends 14 of the blade, al-

though set in somewhat therefrom, the band 16 is formed with two holes17 and 18, the former being a true circle in shape, and the latter beingelongated or substantially elliptical in shape. Intermediate the holes'17. and 18 an angular hook or spur 19 is punched or formed out of thematerial of the band 16. The base plate 10 of the razor is provided withoppositely, arranged studs 20 and 21, and between the same a rectangularpreferably oblong opening 22, the studs cooperating With' the holes 17and 18 and the opening being designed to receive the hook or spur.

The device may be manipulated as follows :-To secure the desiredprojection of the cutting edge 15 the blade is moved back or forth inthe strap 16 the proper extent. Thereafter the blade holder with theblade therein is positioned over the base plate 10, as shown in Fig. 1,with thev spur 19 over the opening 22' and the holes 17 and 18 over thestuds 20 and 21, respectively.

' Then the spur is passed through the opening 22 and the blade holdermoved to the left (Fig. 2) whereby the spur will engage the under faceof plate 10, the elongated hole 18 will ermit such lateral movement ofthe blade older, and finally the hole 17 will snap over and onto thestud 20 and the plate holder will.be firmly secured to the .plate 10. Inthis position of the parts the inner end of the elongated ,hole .18 isapproximately at the point 18, while the outer end of the hole 18 orrather the wall thereof will engage the outer periphery of the stud 21.To release the blade holder from plate 10, the left hand end of theholder is raised so as to clear'the hole 17 of the stud 20, whereuponthe holder is moved to the right until the spur is free of the underface of the late 10, and then the holder may be raised mm the plate 10,

WVhat I claim is 1. A razor blade holder, comprising an adjustable strapembracing the blade, and means whereby the strap may be removablysecured to a part of a razor.

2. A razor blade holder, comprising a strap having its opposite endsturned over the ends of the blade, said strap capable of adjustment inrelation to the edge of said blade and means in the strap for removablysecuring the same to apart of a razor.

A razor blade holder, comprising a strap embracing the blade and meanswhereby the strap maybe removably secured to a part of a razor, incombination with the base plate of a razor, and means thereoncooperating with the means of the strap for removably securing theholder to the plate.

4. In a device of the character described, the combination with the baseplate of a razor having a central opening and oppositely disposed studs,of a blade holder having a central spur for engaging said opening andoppositely disposed holes for engagement with said studs.

5. In a device of the character described, the combination with the baseplate of a razor having a central rectangular opening and oppositelydisposed studs, of a blade holder having a central bent spur forengaging said opening and oppositely disposed differently shaped holesfor engagement with said studs.

In testimony whereof I have afiixed my signature in presence of twowitnessesl CLARIoE FRANOK, PAULA WEBBER.
